Comment # 8 on bug 1123699 from Joachim Werner

Since a week or two ago, the default network on an frequently updated
Tumbleweed I'm running is not automatically coming up any more. Would this be a
separate bug report (because it can't be related _only_ to the YaST problem) or
do you think it has the same root cause?

In my case, the default network exists from the original installation and can
be started manually. It just doesn't auto-start at boot time any more.
